Which statement is true regarding the obscuring of headlamp lenses?

The correct statement is that the obscuring of headlamp lenses applies only to vehicles manufactured in 2013 and later. This is significant because there have been ongoing developments in headlamp technology and regulations regarding vehicle safety over the years.

For vehicles manufactured after 2013, regulatory standards may be stricter regarding visibility and headlamp performance due to advancements in the materials used for manufacturing and the designs implemented. These regulations ensure that the headlamps provide adequate illumination and are not obscured by dirt, damage, or other factors that could impair performance.

Understanding the specifics of obscuring applies to newer models helps inspectors determine compliance with safety standards more effectively, ensuring that these vehicles can provide optimal visibility on the road. Hence, the focus is specific to the model year in question.

The context regarding older vehicles or those with damage is less relevant since the regulation specifically concerns the model year in terms of design and technological standards associated with headlamps.
